Detailed Description

template<typename traj_t>
class ActsTrk::detail::PixelClusterCalibratorCommon< traj_t >

the common base class of a PixelClusterCalibrator.

the class provides common convenience functions to get the detector element for a certain module, and Lorentz angle corrected incidence angles relative to the module reference frame, provides the pixel ID helper and the shift due to the Lorentz angle.

◆ calibrate()

template<typename traj_t>

		const xAOD::PixelCluster &	cluster,
		const InDetDD::SiDetectorElement &	detElement,
		const std::pair< float, float > &	tan_incident_angles ) const

inlineprotected

single calibrate method serving OnTrack and OnBoundState cluster calibration

Parameters

gctx	the geometry context
cctx	the calibration context
cluster	the uncalibrated pixel cluster
detElement	the detector element of the corresponding module
tan_incident_angles	tan of the Lorentz angle corrected incidence angles in local x and local y which are the projections of the trajectory on the surface. this is the method the derived class should overload. The default method is equivalent to the passThrough calibrator, with likely more overhead.

Returns: calibrated positions and corresponding covariance.
